Outline Project Overview Design Factors Model Spreadsheet Results Conclusion
50gpm flow (~26million gal/yr) Ave person – 0.07gal/min This is why I & I is a problem Those interested in conveyance – capacity 2. water treatment – additional flow during rains/design + operate Everyone else - $$$ (1gpm = ~800$/yr) (with $1.1631/100cfs)
Design Factors Pipe age Empirical coefficient Sewer type Pipe area Soil properties
Conclusions/Future Work Process provides good starting areas GIS a needed tool for analysis Future: Correlate spreadsheet to field data
